On issues on protecting our rights, Rand Paul is the only one in the Republican Party doing that. I wouldn't be surprised if a majority of US citizens agree with Rand Paul on these issues.
Releasing all information doesn't necessarily mean we could get the results expected.
I would characterize this as "Randstanding". IMO this is being emphasized as part of his campaign highlighting his libeertarian streak and not necessarily with the intent of the best interests of the people of the US. It will get him the truther vote though.
